BRONZING MACHINE.

SPECIFICATION forming part of Letters Patent'No. 306,605, dated October14, 1884-.

Application filed March 10, 1884. (No model.)

To aZZ whom itmcty concern:

Be it known that 1, WILLIAM E. HALLEN' BECK, of the city of Jersey City,county of Hudson,and State of New Jersey, have invented an ImprovedBronzing Attachment to Cylinder PrintingPresses, and I do declare thatthe following is afull, clear, and exact description of the same,reference being had to the aecompanying drawings, forming part of thisspecifieation.

My invention relates to a bronzing attachment to cylinderprinting-presses which can be readily attached to and detached from anycylinder printingrpress, thus obviatingthe necessity of complicatedbronzing-maehines.

Figure 1 shows my improved bronzing device as applied to a cylinderprinting-press. Fig. 2 shows an enlarged side view of the attachment.Fig. 3 shows a central vertical section of the attachment in the planeof the line as :0, Fig. 4. Fig. 4 shows a rear view of the bronzingattachment, partly broken away, showing the interior construction. Fig.5 shows a front view of the case A, showing also rubber strips andopenings.

Like letters of reference, wherever they oc cur, indicate correspondingparts in all the figures.

My attachment consists of case A, bronzing and distributing rollers B B,cleaning or brushaccumulation of the bronze-powder in the hair of thebrush-rollers, apron E, trough or feed F, into which is placed thebronze, and forks z z, controlling the vibratory movement.

on is a flexible rubber lip, extending the length of the bottom edge ofthe attachment, touching the cylinder of the printing-press; n, flexiblerubber lip extending the length of the top edge of the attachment, sameside.

0 0 are strips of flexible rubber on each end of the attachment, sameside.

It klc k are flexible rubber strips at bottom of openings, also on sameside of the attachment.

The flexible rubber lips and strips indicated by letters m, n, 0 0, andkklclc are tightly fastened to the attachment, as shown in Fig. 3, andwhen the attachment is adjusted to the printingpress they bear evenlyand lightly against the cylinder, thus preventing the escape of thebronze.

p is top of attachment, which can be re moved.

f ff f are setscrews and springs for adjusting at will the rollers tothe cylinder of the printing-press.

c e e c are openings running the length of the attachment, and throughwhich project the bronzing, distributing, and brushing rollerssufficient to touch the printed sheet on the cylinder of theprinting-press.

y is a cam pulley, driving the bronzingroller only when desired.

Mode of operation: The preparation for printing the paper is the same aswith other work. WVhenready to be used, the bronzing and distributingrollers B B and the cleaning rollers C G are placed in their properpositions, and the attachment is then adjusted to the delivery end ofthe printing-press, against the cylinder, and firmly bolted to theledges 88, as shown in drawings, Fig. 1. The rollers can be delicatelyadjusted to the cylinder by means of set-screws and springs f f f f. Thebronze is placed in the feed or trough F. The paper is fed upon thepress and is carried around the cylinder, as in ordinary printing.Immediately upon leaving the printing-form on the bed of the press, itpasses between. the cylinder and the attachment, (instead of beingdelivered upon the fly,) and, while passing, the bronze is applied bybronzing-roller B. By means of an elastic band on cam-pulley y thebronzing-roller B can be regulated to run only when the surfacerequiring bronzing is pass ing. That the distribution may be thoroughand complete, the roller B is also used, being driven by band frompulley on roller B. Each roller is driven to turn in an oppositedirection to that of the cylinder of the pl'intingpress.

Immediately upon the bronze being applied and distributed, and whilepassing, the paper is brushed and cleaned by brush-rollers O O, roller 0being driven by suitable gearing and roller 0 by band from pulley onroller 0. These rollers are also driven to turn in an opposite directionto that of the cylinder of the printing-press. By means of the vibratorymovement governed by forks z z, the bronze is applied to and distributedupon the paper in an even and thorough manner, completely cover- The ingthe heaviest and densest surface.

brush-rollers being also governed by the vibratorymovement, the paper isperfectly cleaned. Immediately after passing the cleaning-rollers, thesheet is delivered to the fly in the usual manner; hence it will be seenthat by means of my attachment thus applied to and operated by theprinting-press I accomplish in one operation both the printing andbronzing, saving thereby one separate handling of the sheets and theemployment and expense of the operating machinery of the usualbronzing-machine, as the printing-press is thus made to perform part ofthe work (as well as the saving of once handling the sheets) of theusual bronzing-machine. The escape of bronze is prevented by means ofstrips of flexible rubber attached to bottom and top edges and at bot--tom edge of each opening, and on each end of the bronzing side of theattachment lightly and evenly touching the cylinder of the press. Thesurplus bronze brushed from the paper and that combed from thecleaning-rollers C O by comb D falls upon apron E, and is carried troughor down to feed F.

I am aware that bronzing-machines are made in which bronzing,distributing, polishing, and brushing rollers are employed, suitablyincased and operated in combination with various other mechanism,whichaltogether constitute bronzing-machines, but not connected di- 0 rectlywith a printing-pressas, for instance, in the cases of L. Poirier, No.194,261; B. G. George, No. 90,521; E. F. Benton, No. 122,216, andothers. Therefore I do not claim,broadly,

a bronzing-maehine consisting of bronzing, dis- 5 What I do claim as newand useful, and de- 40 sire to secure by Letters Patent, is

In connection with cylinder printing-presses, the bronzing attachmentconsisting of bronzing and distributing rollers B B, cleaning or brushrollers O O, and cam 1, substan- 4 5 tially in the manner and for thepurposes described.

In testimony that I claim the foregoing I have hereunto set my hand.
